Nursery contributed plant descriptions

Curly leaves form a wonderful spiral effect. It is a slower-growing plant that will take a couple of years to develop on a green roof; very much worth the wait. The flowers are lower and larger than other Alliums. Pollinators love!
Butterflies and bees love these fuzzy little lavender pompons blooming in mid-summer over neat green foliage. Although most alliums didn't become popular until the last 25 years, in 1866 Boston's E.S. Rand included German garlic in his Bulbs, and in 1900 Liberty Hyde Bailey listed it as one of just six "in general cultivation." 12-18", zones 4a-7b(9bWC)
